Abstract
This experiment was carried out in order to determine proper plant growth regulators (PGR) and their concentrations for direct shoot induction and somatic embryogenesis from leaf tissue cultures of Muscari armeniacum 'Early Giant'. Direct shoot formation from the leaf explant culture was effective only on a half-strength MS medium containing $0.1mg{\cdot}L^{-1}$ 2,4-D, while embryogenesis was occurred on a half-strength MS medium containing $0.1{\sim}1.0mg{\cdot}L^{-1}$ IPA or without PGR. The regenerated bulblets derived from embryos or shoots were harvested and transplanted into a greenhouse. The sprouting percentage of bulblets obtained from different culture media ranged from 80 to 100% and growth of quality bulblets was enhanced when the bulblets were harvested from the medium containing $0.1mg{\cdot}L^{-1}$ NAA and $1.0{\sim}3.0mg{\cdot}L^{-1}$ IPA.
